How East Green Energy quadrupled an existing solar project
Running a poultry farm day and night consumes a lot of energy. When energy prices keep rising, every kilowatt counts. After setting up a UK poultry farm with 124 kWp of solar power, East Green Energy came back with iwell's battery storage and EMS. A ~£150,000 solar project turned into a ~£600,000 solar-and-storage solution, cutting the customer's energy bill by £31,000 a year.
About East Green Energy
East Green Energy is a UK-based solar and renewable energy installer that guides businesses through the entire process: from design and installation to long-term performance. They work with agricultural and commercial clients who want to take control of their own energy supply. As an iwell partner, East Green Energy offers its clients not just solar, but a complete energy solution - including battery storage and smart energy management.
The challenge
The installation for the poultry farm worked well, but the farm's energy consumption kept growing, and with it, the dependence on an increasingly expensive grid. The existing solar array was only taking the edge off daytime bills.
The challenge was twofold.
-
On its own, the existing solar system was not making a meaningful dent in the farm's grid consumption.
-
Grid import constraints meant there was a ceiling on how much additional solar could be added without overloading the connection.
East Green Energy asked the right question: what if battery storage could change the equation entirely?
"For other UK solar installers, this case shows what's possible inside the customer base you already have. Existing solar customers are exposed to the same rising grid costs as everyone else. Adding battery storage means we can fully solve the energy challenge our customer is facing - delivering a solution that meets their needs today and tomorrow"

The solution
East Green partnered with iwell to get the most out of the site:
- They added three iwell all-in-one BESS units - each 105 kW / 233 kWh combined with iwell's EMS.
- The battery storage made it possible to install an additional 300 kWp of solar - bringing the total system from 124 kWp to 424 kWp - without overloading the grid connection.
- iwell's EMS manages the system automatically using solar curtailment as the primary function: it ensures that solar generation is stored intelligently and released when the farm needs it most, minimising what gets drawn from the grid.
Same site. Bigger impact.
For the poultry farmer, the impact is seamless. There's no change to daily operations - just significantly lower energy bills arriving at the end of the month. The site now runs on far more of its own sun, saving £31,000 a year with a 3.4-year payback.
For East Green Energy, the impact was equally significant: what had started as a £150,000 solar project grew into a £600,000 energy project by adding batteries.
This project shows the value of thinking beyond solar: solving the whole energy problem creates more value for everyone - lower costs for the customer and a fourfold increase in project value for East Green Energy.
